The Cartel-Fringe Equilibrium with Sluggish Demand

The demand for some products, such as energy, does not instantaneously respond to price changes. In fact, sluggishness of the demand is an important characteristic of energy and oil markets. This study examines the effect of demand sluggishness on the price and output of a fossil fuel industry in which a cartel and a fringe firm supply in the market. The cartel has larger reserves and less cost...

Positioning and localization of two-wavelength interferograms for wavefront reconstruction with volume holographic media.

This work studies both theoretically and experimentally the formation of the contour interference patterns generated by a two-wavelength real-time holographic interferometer. The resulting contour interference fringes are due to the intersection of the measured surface with parallel, equally spaced planes of constant elevation. The theoretical analysis describes how the spatial frequency of the...

Windowed Fourier transform for fringe pattern analysis: addendum.

Novel approaches based on windowed Fourier transform for demodulation of fringe patterns were previously presented [Appl. Opt. 43, 2695-2702 (2004)], where extraction of phase and phase derivatives from either phase-shifted fringe patterns or a single-carrier fringe pattern was the main focus. I show that the same methods can be applied to process a single closed-fringe pattern in either noise ...

Selective regulation of Notch ligands during angiogenesis is mediated by vimentin.

Notch signaling is a key regulator of angiogenesis, in which sprouting is regulated by an equilibrium between inhibitory Dll4-Notch signaling and promoting Jagged-Notch signaling. Whereas Fringe proteins modify Notch receptors and strengthen their activation by Dll4 ligands, other mechanisms balancing Jagged and Dll4 signaling are yet to be described. The intermediate filament protein vimentin,...
